It is impossible from Fairmaire's description to know whether 

 his species has a conical horn on each side of the j^rothorax or 

 one in the centre ; if on both sides, as in our e.xample, I see no 

 reason for separating it generically from Ceresa ajfinis or C. 

 cavicornis ; if however, the horn is in the centre (a conical 

 prominence on the anterior part of the prothorax), the species 

 might be an abnormal form of Hilie or a Potnia.
